Joey Barton – Est. £1.4 million, Tyneside

Joey Barton, a former Premier League player turned football manager, has successfully leveraged his career to grow his fortune. Throughout his playing days, he made an impressive 269 Premier League appearances, with 130 of them in a Manchester City shirt after rising through their youth ranks and debuting in 2002.

Despite a career not without its share of controversy, Barton made news a few years back when he listed his luxurious Tyneside estate for nearly £1.4 million. The seven-bedroom mansion boasted an eye-catching 9-foot-6-inch aquarium, and Barton was even looking to add an extra £100,000 to the sale price for the fish tank itself.
